How do you drive traffic to your blog?

I am trying to drive more traffic to my blog and wondering how others do it. I am a member of several blogging networks and comment on those. I participate in weekly memes and post links and visit/comment on other blogs. I also update posts daily. What else can I do? I see other mom blogs getting hundreds of hits a day and I am getting 5-10 on average. Some days a little more. Any suggestions? My blog is about homeschooling and parenting younger kids. Thanks in advance for any advice.
